Question 1

Is EPI intercepting aerial threats, and if not, what is its advantage ?

Accepted Answer

Is EPI intercepting aerial threats, and if not, what is its advantage ?

EPI is not actively or kinetically intercepting any threats. Instead, it definitely and continuously jams GNSS over wide areas, especially around strategic infrastructures, so that GNSS guided munitions, drones and missiles, will lose their last kilometers precision, and therefore effectively miss the infrastructures' soft spots.

What good does it serve, if it does not intercept, and there is a hit on the ground ?

How come nobody did it already in the hottest arenas ? It sounds so simple and straightforward...

How do you know when and where to turn on such country wide jamming ?

How do you deploy hundreds of jammers over vast open areas ? How do you manage electric energy in the open, and how do you guard the units from theft and vandalism ?

Can EPI protect all buildings and civilians in a city or town ?

Why is EPI necessary ? Why simple high power GPS jamming or spoofing is not enough to jam the navigation of the incoming UAVs and drones ?

Question 2

What good does it serve, if it does not intercept, and there is a hit on the ground ?

Accepted Answer

EPI is intended to mitigate the accuracy of the threats, thereby causing the hit to be more statistical than surgical. Sometimes a few meters deflection is enogh, and often several tens of meters will do it. When deployed correctly EPI can comply very well with its intention.

Question 3

How come nobody did it already in the hottest arenas ? It sounds so simple and straightforward...

Accepted Answer

Good question. The main arena was Ukraine, and they probably couldn't manage it correctly and in time, thereby losing so many infrastructures. At some stage it was too late to implement. Israel had different approach based on multi level air defense systems and air superiority.

It is in evolution...

Question 4

How do you know when and where to turn on such country wide jamming ?

Accepted Answer

Every country has its air defense warning system. EPI can be integrated with these warning systems, locally and country wide, or manually turned on locally upon information of imminent attacks, or ongoing explosions.

Question 5

How do you deploy hundreds of jammers over vast open areas ? How do you manage electric energy in the open, and how do you guard the units from theft and vandalism ?

Accepted Answer

Epi jamming units are intended for wartime. They will usually not be deployed before immediate need. The deployment is planned and tested in advance, with equipment usually stored until needed. Deployment can be done in several days. Energy is an important issue and there are several solutions. The most straightforward and fastest way is to install units on low cost cars, which solves all these issues. Cheaper methods are available of course, depending on the total number of infrastructures and required jammers etc.

Question 6

Can EPI  protect all buildings and civilians in a city or town ?

Accepted Answer

EPI is not intended to protect simple buildings, houses, or civilians getting hurt. When a country is at war, it's impossible to protect all buildings, and there are much more critically important assets to protect. Conventional air defense also has limited efficiency at intercepting threats...

Question 7

Why is EPI necessary ? Why simple high power GPS jamming or spoofing is not enough to jam the navigation of the incoming UAVs and drones ?

Accepted Answer

Because those are also equipped with a special multi element GPS antenna called CRPA. A 4 elements CRPA can defeat 3 jammers from different directions. 4 jammers will usually defeat this antenna as well.
